Thickening of tissue and discoloration
If the infection occurs on the fingernail or toenail, then nails become thick, and the color and shape of the nails also start to change. The disease is identified by the change in color of the nail, which starts to look yellow or brown or white. The nails become thicker and can be cracked or break. Nails can also get crumbled or even disappeared. Infection in this area is usually not painful, but in some cases, the person can experience pain.
